Mesoscale Discussion 0080
NWS Storm Prediction Center Norman OK
1205 PM CST Sun Feb 14 2021
Areas affected...Much of West Texas...the Texas South Plains...and
southern/central Oklahoma
Concerning...Heavy snow
Valid 141805Z - 150000Z
SUMMARY...Areas of moderate to heavy snow are expected to increase
in coverage this afternoon in portions of the discussion area
through 00Z.
DISCUSSION...Latest observations/radar mosaic imagery indicates
widespread areas of light to moderate snow bands migrating
east-northeastward across the discussion area. Embedded heavier
snow was also reported - most recently across Altus/Lawton/Hobart in
southwestern Oklahoma and near Odessa in southwest Texas. The bands
across southwestern Oklahoma may produce 1+ inch-per-hour snowfall
rates as they expand northeastward toward the I-35 corridor in
central Oklahoma over the next couple hours.
Farther southwest, models/observations indicate that coverage of
moderate to heavy snow will increase over time from the Texas Big
Country northeastward to western North Texas as forcing for ascent
associated with a mid-level trough over New Mexico overspreads the
area. A gradual increase of 700hPa flow in central Texas will also
contribute to increased ascent in this region. The greater chance
of 1 inch-per-hour rates will generally increase along the I-20
corridor in west Texas (Midland to Abilene to Fort Worth) in the
21-00Z timeframe.
